But that's only useful if it's previously formatted at the correct size. In this case, I don't actually know how many sectors the drive has. :-(

Good idea. I did, but am only finding "135 MB". And I know that's marketing MB, 1000/bytes per.

I know it's really a 128MB, but I don't know exactly how many sectors. I did find a few pages on it, including one as recent as 2011, but they don't mention sectors.

I manually wrote out to 7FFFF sectors, I think, before errors, so I guess that's it. It's a few sectors larger than what OS-9 can use, but dEd was still able to get that far.
